Finally, the last remaining steering shimmy is gone!!! It turns out the last place that balanced the 31's only did a static balance. I didn't know the difference. Now after being balanced on a highspeed, staticly; the Jeep rides beautifully now. There is no shaking in the steering at any speed, any legal speed
Did discover though that one of the tires cannot be balanced. The Tech said it was a bad tire, so its on the back. I drove it on the highway, and although one tire is out of round, and unbalanced I couldn't feel anything in the steering wheel OR in the seat.
If it does get bad again, I'll have to replace the two rear tires. Shame I went with expensive rubber though.
Good Year Silent Armor Wranglers arn't cheap, but oh well. I got them second hand so I don't even have the receipt.
